AIR CONDITIONER FOR AUTOMOBILES Filed Dec. 9, 1939 2 Sheets-Sheet 2 Inventor WAY/v5 R. BOLA/V,

A tiomeys Patented Dec. 3, 1940 UNITED STATES PATENT: OFFICE 4 Claims.

This invention relates to air conditioners and an object of the present invention is to provide a device of this character which may be readily adapted for conditioning or cooling the interior of automobile bodies. 1

Among the objects of the invention is the provision of an air conditioner for automobiles which may be readily mounted on an automobile, is comparatively simple in construction, and other- Wise well adapted for the purpose designed.

The invention together with its objects and advantages will bebest understood from a study of the following description taken in connection with the accompanying drawings wherein- Figure 1 is an elevational view illustrating the application of the invention.

Figure 2 is a side elevational view further illustrating the invention.

Figure 3 is a top plan view of the device.

Figure 4 is an'enlarged detail view partly in section and partly in elevation illustrating certain details hereinafter more'fully referred to, and

Figure 5 is a vertical sectional view taken substantially on the line 5-4 of Figure 4.

Referring more in detail to the'drawings it will be seen that in the preferred embodiment thereof the air conditioner comprises a casing 15 having in the upper part thereof a water tank or reservoir 6, with the remaining portion of .the casing forming an air duct 1.

At one side edge thereof the casing I is con;- structed to provide what may be termed a flared air inlet 8 for the duct 1.

Arranged in the lower portion of the casing and in alignment with the air inlet,opening 8 is an air moistening and filtering device indicated generally by the reference numeral 8.

The device 9 comprises a pair of spaced-apart screens Ill, and the space between the screensis filled with fibrous material II. The device 8 is removably held in place through the medium of suitable anchors l2.

For saturating the fibrous material II with water from the tank ,6 there is provided a spout l3 that terminates within the space between the screens 9 as shown in Figure 4, and between the spout I3 and the drain or discharge opening I! in the bottom of the tank 6 is a control valve I5.

An operating rod I6 is provided for the valve l5 and the knob-equipped end ll of the valveoperating rod I6 is disposed exteriorly of the easing 5 as best shown in Figure 4 sothat valve can be manually operated conveniently. A

In the top thereof the casing I is provided with desired side thereof.

an opening I! for the duct 1 and inserted in the duct I at the opening I! is one end of an airdischarge neck or tube I! that is held in the desired position of rotatable adjustment through the medium of a set screw 20. 6 For the free end of the discharge neck or tube I 9 there is provided a discharge nozzle 2| that is preferably of the shape shown and embodies a tubular shank portion 22 that fits snugly within the discharge tube or neck I9 as shown. 10 Pivotally mounted within the nozzle 2| are louvers 23 which can be conveniently adjusted for directing the air current in the direction desired.

As shown in the drawings the device is adapted to be mounted exteriorly of the automobile at the To that end the casing i at the top and bottom thereof is provided with loops 24 for accommodating straps 25 that serve to connect with the said loops 24 hooks 28.

Preferably at least one pair of hooks is provided for the bottom, and one pair of hooks is provided for the top of the-casing, and as shown in Figured, the hooks 26 at the top of the device engage over the edge of the automobile door 21 at the bottom of the window ope ngs in the door, while the lower hooks 26 engage over the lower or bottom edge of the door as shown.

To prevent marring of the door 2'! protector strips 28 of rubber or other suitable material are 30 mounted on one side of the case 5 for disposition between said side of the case 5 and the exterior of the door 21 as also clearly shown in Figure 2. ?trips 28 serve also as tension devices for straps i. 1

When in use the air discharge tube or neck I! extends through the open window of the vehicle into the interior thereof as suggested. g

In operation, when the vehicle is in motion air passes through the opening 8 to flow through the o conduit 1. In its passage through the conduit I the air passes through the fibrous material II where it absorbs moisture and has removed therefrom foreign matter so that the air, when discharged through the nozzle 2| into the interior of the automobile will be free of foreign matter, i

will be properly moistened, and will tend to lower the temperature within the automobile body to the comfort of the occupants thereof.

The casing 5 is also provided with a suitable drain opening 29 so that any water accumulating in the bottom of the casing may readily drain therefrom.

It will also be apparent that with this device the cooled, clean air discharging from the nozzle 2 2| may be directed toward any part of the interior oi the automobile. It will be further appreciated that when it is desired to close the window through which the air outlet or tube 1! extends, all that is necessary is to rotate the latter to move the same to a position exterior of the automobile body, thus permitting the window to be fully closed. I 1

The tank part 6 of the device is also provided in the top thereof with a suitable filling neck 30 as shown.

It is thought that a clear understanding of the construction, utility and advantages of an invention of this character will be had without a more detailed description thereof.

Having thus described the claimed as new is:

1. An air conditioning device for a motor vehicle comprising a casing, means forsupporting invention what is the casing from a door of the vehicle with thecasing at the exterior side of the lower part of the door, said casing having an opening 'in'its front for the admission of air as the vehicle travels along, and said casing having an outlet opening in its top, means for conditioning the air as it passes through the casing, a pipe having one end rotatably supported in the outlet opening and a nozzle at the other end of the pipe, said nozzle extending through the window opening of the do r when the pipe is in one position and by partly otating the pipe the nozzle can be positioned exterior of the door.

2. An air conditioning device for a motor vehicle comprising a casing, straps connected to the top and bottom parts of the casing, hooks at the ends of the straps for engaging portions of a I door of the vehicle to support the casing at the exterior side of the lower part of the door, said casing having an opening in its front for the a mission of air while the vehicle is traveling alo a pipein communication with the top of the casing andadapted to pass through the window opening of 'the door and air conditioning means in the casing.

3. An air conditioning device of the class described comprising a casing, a water tank in the top of the casing and spaced from the rear wall thereof, the front wall of the casing having an inlet opening therein below the tank, the top of the casing having an outlet opening in communication with that part of the casing between the tank and the rear wall, filter means extending from the bottom of the tank to the bottom of the casing and also extending from one side wall of the casing to the other side thereof and valve control means for leading water from the tank to said means.

4. Air conditioning means of the class described comprising a casing, a water tank in the top thereof and spaced from the rear wall there-' of, said casing having an opening for the admission of air in its front and under the tank, said tank with portions of the side walls and the bottom and rear wall of the casing forming a passage for the air which extends under the tank and up between the tank and the rear wall of the casing, said tank having an outlet opening in its top which is in communication with .the space between the tank and the rear wall of the casing,

an elbow-shaped pipe having one end rotatablv arranged in the outlet opening, filter means extending across that part of the passage which extends under the tank and valve control means for leading liquid from the tank to said filter means.
